I want to switch in an extra 22n cap for C3 (in parallel) using a switch.  What is the right switch to use ?  spdt ?  dpdt ?   with led ?

how to do this ??

Here's one way to do it that is pretty clean.

so, i tried this and it is very subtle.   i kept c3 (22n) in the board and installed the switch as shown in your pic using a 68n cap.    so, this should be that i get either 22n or 90n when switched.  no ?   or, would i get a greater difference if i removed c3 from the board and used the 68n on the switch and no cap in c3 ?
